  "id": "MLC-T-CHM-003246",
  "term": "Diradicals",
  "field": "Chemistry",
  "definition": "Molecular species possessing two unpaired electrons, where the two radical centers are sufficiently separated that they do not strongly interact. These can exist in either a singlet state, where the electron spins are paired, or a triplet state, where the spins are parallel. The energy difference between these states dictates their reactivity and spectroscopic properties.",
